Product Details

The LTM8053 is a 40VIN, 3.5A continuous, 6A peak step-down µModule® (power module) regulator. Included in the package are the switching controller, power switches, inductor, and all support components. Operating over an input voltage range of 3.4V to 40V, the LTM8053 / LTM8053- 1 supports an output voltage range of 0.97V to 15V and a switching frequency range of 200kHz to 3MHz, each set by a single resistor. Only the input and output filter capacitors are needed to finish the design. The LTM8053-1 can operate in forced continuous mode.

The low profile package enables utilization of unused space on the bottom of PC boards for high density point of load regulation. The LTM8053 / LTM8053-1 is packaged in a thermally enhanced, compact over-molded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8053 / LTM8053-1 is RoHS compliant.
